extension was 1234, then the first shared appearance would be 12341, and the
second would be 12342, etc. This is not a requirement, but something similar
should be considered to reduce confusion when troubleshooting.
Configuration in Interaction Administrator for shared lines is covered in the 2.4
documentation.
1.1.5.7 Line Roll-Down (Polycom firmware 1.5.x and beyond)
Post 1.5.x firmware, the Polycom phones have the ability for inbound calls to "ring
down," the line keys. This behavior is very similar to legacy PBX operations where
each user had a roll-over line. If the primary line is busy, a second incoming call
would "roll-down," to the next line key. This behavior can be configured for as
many line keys as the Polycom phone has.
Configuration for this feature is on a per line basis and can be found at the end of
each line definition in the phone specific config file. Two settings are required:
1). reg.1.lineKeys="3"
2). reg.1.callsPerLineKey="1"
The only requirement for this functionality in Interaction Administrator is to configure
the maximum call appearances on the specific station to match the maximum
number of line keys that you'd defined.
As calls are delivered you will be able to move between them using the line keys.
1.1.5.8 Forwarding and Do Not Disturb Buttons Status Sync
This functionality is being integrated to work with the client. When DND is set
through the phone, the client will update the user status to DND. This behaves
similarly if the status is set via the client. Neither DND or Forward functionality is
currently in 3.0 SU3. Until it is released, these buttons are not supported with the
use of managed phones.
1.1.5.9 Conferencing Under TLS
This tells phone phone how many line appearances each line
definition should take. In this case, once the phone has been
booted up, this line will occupy the first three line keys on the
phone.
This tells the phone to allow one call per line. This can be
increased but will not mimic legacy PBX behavior. As the next
call comes in, it will ring the second line key, and then the
third, up until the maximum is reached as specified in the
above parameter.
